Same image, two ways to render it as sound. The thesis documents explain when to use each.
Rileva i peaks (stars/galaxies): each source = one spatialized drop. Sparse, "rain of stars".
Scansiona l'intero campo as continuous texture: every region contributes. Dense, ideal for nebulae.
Sources when the image is a deep sky with distinct points (star counts/positions): you hear the individual objects, scattered. Campo when the overall texture matters (nebulae, gradients): you hear a continuous fabric. Both are parametric and reproducible (export .txt); dichiari quale usi.
Step 3 = space: the X position becomes stereo (left↔right); distance (darker = farther) increases reverb. Listen on headphones.
